System is fallback for PUBLIC that fails. But as my conversation with
Murray showed, it's probably better to tell authors that the two had
_better_ be equivalent as applications get the choice of resolution
mechanisms. I think my example was quite realistic, and shows that some
SYSTEM IDs should be handled before some PUBLIC IDs, and vice versa....
